I know the ram is compatible. I have 2 1gb sticks. Both are the same. The first stick I bought with the rest of the parts. I recently bought the 2nd stick, exact copy of the first from Corsair. Not sure on the model of my MB. Just that it is a biostar. Would the power source be a problem only at start up? Cause once the machine boots up after the few failed attempts it works flawlessly. Did the mem tests and no errors returned.
